New Delhi: Aided by raging cyclone Mahasen, south west monsoon, the lifeline for millions of farmers in India, is all set to bring showers over the Andaman Sea in the next two to three days.

"Conditions are favourable for advance of south west monsoon over Andaman Sea and adjoining sea areas during next 2-3 days," the India Meteorological Department (IMD) said on Tuesday.

Weather scientists said cyclone Mahasen, which has been churning the Bay of Bengal clocking wind speed of upto 75 km per hour, is expected to help in the timely onset of monsoon over Andaman Sea.

Andaman and Nicobar Islands usually receive monsoon showers between May 10 and May 20.

Under the influence of Mahasen which is likely to lash many parts of coastal Odisha and some other areas, Andaman and Nicobar Islands region has been experiencing heavy rainfall and squally winds of upto 40-45 km per hour.

Last month, the weather office had forecast normal monsoon this year with overall rainfall expected to be 98 percent of the long period average. Monsoon is crucial for the kharif crops such as rice, soyabean, cotton and maize because almost 60 percent of the farm land in the country is rained.
